JOHN KELLY AND LEO. F. HORR-ELL, OF RED BUD, ILLINOIS.

PLOW-DOUBLETREEQ SPECIFICATION forming part of Letters Patent No. 425,676, dated April 15, 1890.

Application filed February 3, 1890. Serial No. 338,987. (No model.)

To all whom it Wmy concern:

Be it known that we, JOHN KELLY and LEO. F. HORRELL, citizens of the United States, residing at Red Bud, in the county of Randolph and State of Illinois, have invented certain new andusefulImprovernents inPlow-Doubletrees; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to doubletrees for plows.

The obj eot of our invention is to construct a strong, light, and cheap doubletree for plows; and to this end the nature of our in-- vention consists of constructions and combinations, all as will hereinafter be set forth in the specification, and particularly pointed out in the claim, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of our doubletree, and Fig; 2 the metal band.

A represents the wooden portion of our doubletree, which is straight on the front edge and oval on the rear edge. To prevent the wood from splitting, rivets a are inserted through the flat side at each end,,as shown in Fig. 1.

Upon the front edge of the wooden portion A, and on each side of the clevis-pin hole B,

are metal spring-piecesO, secured near their rear ends to the wood portion A by means of rivets b, and their front ends extend beyond the end of said wood portion A, and are provided with holes 0, for the purpose hereinafter described.

Along the rear or oval edge is placed a flat metal band D, cutaway a short distance from the ends to form shoulders 61. From the shoulders d the ends are rounded, so as to pass through the holes 0 in the ends of the metal spring-pieces O, and bent outwardly to form hooks E for the singletrees.

It will be seen that by this construction in the seesawing or pulling away from each other of a team the shoulders d will abut against the metal pieces 0 and cause them to act as springs and prevent the pulling out of the hooks E.

Having thus described our invention what we claim, and desire to secure by Letters Patent, is

In a doubletree, the combination of the wooden portion A, metal spring-pieces O,pivoted at one end to said wooden portion, and provided at their other end with holes 0, and the metal band D, having shoulders cl, and rounded ends passing through the holes 0 in the ends of the spring-metal piece'O, and bent outwardly'to form hooks E for the singletrees, substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.

hi JOHN KELLY.

mark LEO. F. HORRELL.
